Method for monitoring the law of illumination of a radar antenna and corresponding device

Abstract

A method for controlling laws of illumination of a radar antenna with adjustable gain and/or phase, suitable for sending and for receiving a radar signal, the method including obtaining a position of an obstacle located in a near field of a beam of the radar antenna according to a direction of aim of said beam, calculating the laws of illumination on sending and on receiving of said radar antenna so as to adjust the direction of the aim of the radar beam while minimizing interaction and/or effects between the beam of the radar antenna and the obstacle, and implementing the calculated laws of illumination on sending and on receiving of the radar antenna.

1 . A method for controlling laws of illumination of a radar antenna with adjustable gain and/or phase, suitable for sending and for receiving a radar signal, the method comprising:
 obtaining a position of an obstacle located in a the near field of a the beam of the radar antenna according to a the direction of the aim of said beam   calculating the laws of illumination on sending and on receiving of said radar antenna so as to adjust the direction of the aim of the radar beam while minimizing interaction and/or effects between the beam of the radar antenna and the obstacle; and   implementing the calculated laws of illumination on sending and on receiving of the radar antenna.   
     
     
         2 . The method according to  claim 1 , wherein the implementing the laws of illumination includes a weighting of the gain of the radar signal sent according to the position of the determined obstacle. 
     
     
         3 . The method according to  claim 1 , wherein the implementing the laws of illumination includes a weighting of the phase of the radar signal sent according to the position of the determined obstacle. 
     
     
         4 . The method according to  claim 1 , wherein the implementing the laws of illumination includes the activation and/or deactivation of modules for illuminating said radar antenna, comprising a deactivation of the illumination modules generating a portion of said antenna entering into interaction with said obstacle. 
     
     
         5 . The method according to  claim 1 , wherein said antenna is of an “active” type. 
     
     
         6 . The method according to  claim 1 , wherein said antenna is of a “passive” type incorporating gain- and/or phase-controlled illumination modules. 
     
     
         7 . The method according to  claim 1 , wherein said antenna is of an electronic scanning type. 
     
     
         8 . A device for controlling the law laws of illumination of a radar antenna of distributed amplification type, characterized in that it is suitable for implementing configured to implement the method as claimed in one of the preceding claims according to  claim 1 . 
     
     
         9 . A method for controlling laws of illumination of a radar antenna of distributed amplification type, the method comprising
 use of a controlling device according to  claim 8 , in an aircraft or a boat.
